[Homer-users] AtlasViewerGUI Hb Concentration Plot

[Jahani, Sahar]

Dear Selena,

Here you can find the instruction for using the overlay function.

1)     Add Homer folders and subfolders to your Matlab path,
2)     Change your Matlab path to the folder where your groupResults.mat is available,
3)     Open AtlasViewerGUI,
4)     Go to tools menu and import your probe.SD file,
5)     Register probe to the surface,
6)     From the Tools menu, select Hb Conc Overlay,
7)     Select an appropriate time range: [tRangeMin tRangeMax]. (The time range which you want to see the averaged Hbo/HbR changes on the Atlas),
8)     From the drop down box in the Image Display section, you can select HbO Conc, HbR Conc and so on. Also, under the drop down box, you are able to specify the colormap range (specifying an appropriate colormap range will result in a complete probe HbO/ HbR overlay on the Atlas), channel numbers (default is displaying all channels), and Condition (put the number of your intended condition) and then press the Enter key.
Hope this will help you.
Please let me know if you have any comments or questions.

Thank you,
Sahar

Dear all,

I have seen on NITRC that the new release of Homer2 (v 2.2) gives the opportunity to overlay images of Hb concentrations on the cortex. Unfortunately, when I try to use this function it does not work properly. So, I would like to ask if you can explain which are the steps to use this function, in order to understand where is my mistake.



Actually, I simply click on HbO or HbR Conc in 'Image display' but I have no results (nothing happens on the screen, it plots only the colorbar), in addition I cannot modify 'condition'.

(I am using v 2.2 with MCR_R2016a 64 bit)



Thank you for your attention,
